OCCT conversion workflows

VRML to glTF / GLB

Convert VRML to glTF / GLB. Prepare source geometry, select the target writer and verify placements and supported attributes.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Read VRML for glTF / GLB output

A VRML-to-glTF / GLB workflow connects the VRML reader to the glTF / GLB writer. Select the model items and output representation needed by the receiving application.

Read WRL or VRML geometry through the OCCT VRML interface. Inspect the mesh content and available placements and appearance before constructing the receiving document. Keep referenced resources accessible during import.

Prepare a scene for glTF or GLB delivery

Use the imported polygonal geometry for mesh exchange or a mesh-capable CAD container. A scene-format change does not create precise CAD surfaces. Identify any interactive behavior or other source features that fall outside the geometry mapping.

Map supported model items into glTF scene nodes and configure the mesh, placements and appearance for browser or application delivery. Decide whether the receiving workflow expects a GLB package or glTF with companion resources. Keep names useful for selection and inspection.

Check the glTF / GLB result

Compare scale, orientation, geometry coverage and supported appearance. Retain the original scene if its behavior or organization must remain available beyond the geometry exported to the target.

Reopen the asset in the target viewer and compare orientation, bounds, assembly placement and visible surface quality. Check material mapping and resource paths. Measure loading cost together with geometric detail so that reducing mesh size does not silently remove required features.

Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.

Conversion integration

Build a VRML to glTF / GLB workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
